Raspberry Pi ADS-B receiver Notificator

I’ve been running a Raspberry Pi with a RTL-SDR USB adapter for a while to capture ADS-B signals from the airplanes that flies over my home. I has been laying on top of my computer with a really bad antenna installation and sent it´s captured data to http://flightradar24.com/

The other day I thought of the installation and that i don´t in a easy way can see if it receives any data, well I can log in to flightradar24 and look at my stats or i can open a telnet session to port 30003 to see the captured data. But it wold be more fun get a more ping notification, when it accuracy hears something.

And what is more rewarding than a blinking LED, that sends it’s blue shimmer in the room.

So i wrote a small Python script that makes a socket connection to the localhost:30003 port, and if it sees some data on the port it blinks a LED. The LED is connected via a 220Ω resistor between ground and GPIO-18.
